LANCE Armstrong will admit to doping throughout his career during an upcoming interview with Oprah Winfrey.
However, it is understand he probably will not go into great detail about specific cases and events.
The announcement that Armstrong agreed to an interview, to air on Winfrey's OWN cable TV network on Thursday, has sparked widespread speculation that he might finally confess to being a drug cheat after years of strenuous denials.
It will be Armstrong's first interview since he was stripped in October of his seven Tour de France titles after the US Anti-Doping Agency (USADA) said he helped orchestrate the most sophisticated doping program in sports history.
Nicole Nichols of Winfrey's OWN network said "no question is off-limits" in the interview, for which Armstrong will not receive any payment.
Last week, The New York Times reported that Armstrong, 41, was considering publicly admitting that he used banned performance-enhancing drugs in an apparent bid to return to competitive sport in marathons and triathlons.
His years of dominance in the sport's greatest race raised cycling's profile in the United States to new heights and gave Armstrong, a cancer survivor, a unique platform to promote cancer awareness and research.
The Lance Armstrong Foundation has raised almost $500 million since its creation in 1997.
In the wake of the allegations, several top sponsors dropped Armstrong and on Nov 14 his name was dropped from the charity he founded, which is now known as the Livestrong Foundation.
